Performing the ADC test the results didn¡¯t look anyway near the graph in the manual.
After doing more scope probing I discovered there isn¡¯t a CLK0 on pin 2 of IC403; but there is CLK2 on pin 14. As I study the QMX+ ?schematic and learning how a Taylor detector works, new to me, I would guess that the I and Q signals are then messed up. Not fully understanding this yet I think the missing CLK0 is the culprit. Can anyone confirm that there should be a CLK0? This then would be caused bu a defective IC204, MS5351M chip. Any thoughts?
